MG Chemicals 8329TFF-50ML, Fast Cure Thermal Adhesive, 45ml Dual Cartridge, Case of 6
MG Chemicals 8329TFF-50ML — Fast Cure Thermal Adhesive, 45ml Dual Cartridge, Case of 6
The MG Chemicals 8329TFF is a 2-part, 1:1 mix ratio thermal epoxy adhesive designed for applications requiring fast processing, strong bonding, and reliable thermal management. With a working time of 5 minutes and a set time of only 15 minutes at room temperature, the 8329TFF is well suited for production environments where throughput matters. Once cured, it forms a hard, durable polymer that is thermally conductive yet electrically insulating — making it the correct choice for bonding heatsinks, LEDs, power modules, and other heat-generating electronic components where electrical isolation must be maintained.
The 8329TFF achieves a thermal conductivity of 0.8 W/(m·K) and is UL 94V-0 registered as flame retardant (UL File# E334302). It bonds well to metals, ceramics, glass, and most plastics used in electronic assemblies. The 50ml dual cartridge format is compatible with standard static mixing tips and pneumatic or manual dispensing guns for consistent mix ratios in production use. The 8329TFF-50ML is sold as a case of 6 cartridges.

Frequently Asked Questions
What is the thermal conductivity of the 8329TFF?
The MG Chemicals 8329TFF has a thermal conductivity of 0.8 W/(m·K). This is appropriate for general heatsink bonding and LED attachment applications. For higher-conductivity requirements, consider the MG Chemicals 8329TCF or silver-filled thermal adhesives.
Is the 8329TFF electrically insulating?
Yes — unlike silver-filled conductive epoxies, the 8329TFF is electrically insulating while remaining thermally conductive. This makes it the correct choice for bonding heatsinks directly to component surfaces where electrical isolation must be maintained between the component and heatsink.
How fast does the 8329TFF cure?
The 8329TFF has a working time of 5 minutes and sets in 15 minutes at room temperature. Cure can be accelerated with mild heat. Full mechanical and thermal properties are reached after complete cure.
What dispensing equipment is compatible with the 50ml dual cartridge?
The 8329TFF-50ML dual cartridge is compatible with standard 50ml 1:1 manual or pneumatic dispensing guns and static mixing tips. This ensures a consistent 1:1 mix ratio during dispensing without manual mixing.
Is the 8329TFF UL listed?
Yes — the 8329TFF is UL 94V-0 registered as flame retardant under UL File# E334302, meeting the flammability requirements for components used in electronic assemblies.
